Today's geomorph features a central chamber (circular in my original conception) with four ground-level entrances and two successively higher bridges or catwalks. I imagined something akin to green-house or botanical garden filled with towering trees. The walkways above the ground floor would pass through different levels of the tree canopy. Of course, there are many other possible interpretations of the tile.
